It should give you a % on the bottle. BP is a British Pharmacopoeia preparation of potassium nitrate for medicinal use, it's not necessarily high purity. L
should be atleast 99.9% A-grade =]

Is that AR grade, or higher?

L
Its the main grade. I've never seen it in any other grade. but if your making gun powder you have to have electric scales, and have the measurments absolutely perfect.

Well I think anything over 80% is probably going to work.

L
no, anything over 90% but you wont get the same gunpowder effect. u need 99.9% to get the real gun powder effect.
It is not very clear what they actually want to do with it. Black powder isn't mentioned, fuses are something else. I wouldn't disagree with you over black powder.
